Defining Triggers
Triggers let you start and stop captures based on date and time, alarms,
and specific network events. Use triggers to capture data while your
Sniffer Portable Professional machine is unattended, such as on
off-hours or weekends, or to start captures when specific events occur,
such as alarm conditions.
IMPORTANT: You cannot enable a trigger when a capture is already
running. If you try to do so, you will receive a Failed to set trigger
error message. Stop any active captures before enabling a new trigger.
You can define three kinds of triggers — start triggers, which will start a
capture session, stop triggers, which will stop a capture session, and
start and stop triggers, which do both.
A start trigger has two elements:
Trigger specification. Specifies what will start a capture session.
Select a predefined trigger specification from a drop-down list, or
create a new one by clicking the Define button.
Capture filter specification. Select a capture filter to use during
the capture. Select one from the Capture Filter list.
A stop trigger has three elements:
Trigger specification. Specifies what will stop a capture session.
Select a predefined trigger specification from a drop-down list, or
create a new one by clicking the Define button.
Trigger delay specification. Specifies how many packets to
capture after the stop trigger event occurs.
Restart option. Check this box to automatically restart capturing
after the stop trigger event occurs.
As with a filter, once you create and name a trigger, you can reuse it
whenever appropriate.
